I feel like the Tf2 Demoman! Cool mechanic. Pretty fun to play and it is very usable with good player feedback. I do think the blast power gives too little movement to the player. It is not much more than the jumping height, and it's vertical as well as the jumping. A combination of horizontal and vertical blast movement would be cool. Also it is kind of ironic that the pretty bomb explosion is almost always behind your back, sad to see. Because it is pretty.

For some ideas: Obviously adding more levels would be cool. Something to think about is air jumping, requiring the player to detonate in the air to get a sort of double jump. Or maybe limiting the amount of mines you can use. Lots of ideas :)

very cool movement mechanic, i think with some levels this could be a lot of fun. Also there should probobly a timer and limit on how many you can spawn since you can now just fly in the sky by spam clicking or by bunching a lot of them on top of eachother.
